Greenhouse effect is a house made of glass which allows the sunlight to come in but prevents the heat from escaping. In cold countries, It is used to grow plants that thrive in hot weather. The name ‘Greenhouse Effect is given as the atmosphere acts like the glass.
Greenhouse gas pollution, through its contribution to global climate change, presents a significant threat to Americans’ health and to the environment upon which our economy and security depends
What is greenhouse effect?
Certain gases such as carbon-di-oxide, nitrous acid and methane are given out by motor vehicle, factories, volcanoes and so on. When they increase in quantity in the atmosphere ,they trap the heat energy coming from sun and do not let it escape. This makes the earth hotter. This phenomonon is called greenhouse effect and the gases which cause greenhouse effect is called greenhouse effect.
What causes greenhouse effect?
- Use of Fossil Fuels: Fossil fuels such as coal, oil, and natural gas have become an essential part of our daily lives. They are widely used in the production of electricity and transportation. When they are burned, the carbon stored within them is released, combining with the oxygen in the air to form carbon dioxide. The increase in population has resulted in an increase in the number of vehicles, which has resulted in an increase in pollution in the atmosphere. When these vehicles run, they emit carbon dioxide, one of the main gases responsible for the increase in the greenhouse effect.
2. Deforestation: Forests cover a large portion of the planet’s green space. Plants and trees absorb carbon dioxide and emit oxygen through the photosynthesis process, which humans and animals require to survive. Large-scale development has resulted in the destruction of trees and forests, forcing people to seek alternative living arrangements. When wood is burned, the carbon stored in it is converted back into carbon dioxide.
3. Population Growth: Over the last few decades, there has been a significant increase in population. As a result, there is now a greater demand for food, clothing, and shelter. New manufacturing hubs have sprung up in cities and towns, releasing harmful gases into the atmosphere and contributing to the greenhouse effect. Furthermore, more people means more use of fossil fuels, which has exacerbated the problem.
4. Farming: Nitrous oxide is a greenhouse gas used in fertiliser that contributes to the greenhouse effect, which leads to global warming.
5. Industrial Waste and Landfills: Industries such as cement production, fertiliser production, coal mining, and oil extraction emit harmful greenhouse gases. In addition, garbage landfills emit carbon dioxide and methane gas, which contribute significantly to the greenhouse effect.
What increases greenhouse gases?
Almost all of the increase in greenhouse gases in the atmosphere over the last 150 years has been attributed to human activity. In the United States, the largest source of greenhouse gas emissions from human activities is the use of fossil fuels for electricity, heat, and transportation.
What are the five major gases that contribute to the greenhouse effect?
Carbon dioxide, methane, nitrous oxide, and water vapour (all of which occur naturally) are the main gases responsible for the greenhouse effect, as are fluorinated gases (which are synthetic). Greenhouse gases have different chemical properties and are removed from the atmosphere through various processes over time.
What are the increased levels of greenhouse gases?
Natural gases, including atmospheric water vapour, methane and carbon dioxide, act as an insulating blanket for the earth by retaining heat from the sun which keeps the earth warm. This is known as ‘the greenhouse effect’, and the gases that cause it are known as ‘greenhouse gases’. Without these gases, the earth would be much colder than it is.
What is global Warming?
Increased concentrations of greenhouse gases in the earth’s atmosphere cause global temperatures to rise. This is known as ‘global warming’.
Global warming is the gradual increase in the average temperature of the earth’s atmosphere caused by an increase in the amount of energy (heat) striking the earth from the sun being trapped in the atmosphere rather than radiated out into space.
The earth’s atmosphere has always acted as a greenhouse, capturing the sun’s heat and allowing the emergence of life forms as we know them, including humans.
The earth would be very cold if we did not have our atmospheric greenhouse. Global warming, on the other hand, is the equivalent of a greenhouse with high efficiency reflective glass installed backwards.
What is climate change?
Climate change refers to long-term, significant changes in the global climate.
The global climate is the interconnected system of the sun, earth, and oceans, wind, rain, and snow, forests, deserts, and savannas, as well as human activity. A place’s climate, say, New York, can be described by its rainfall, changing temperatures throughout the year, and so on.
However, the global climate is more than the “average” of local climates. A description of the global climate includes how rising Pacific temperatures, for example, feed typhoons, which blow harder, drop more rain, and cause more damage, However, it also shifts global ocean currents, causing Antarctica’s ice to melt, causing sea levels to rise gradually until New York is submerged.
It is because of this systemic interconnectedness that global climate change is both important and complicated.
Which are the primary sources of GHGs and black carbon?
The most significant sources of GHGs and black carbon are fossil fuels and related coal and petroleum uses (power generation, industry, transportation, buildings).
Agriculture is the second most important source (animals – cows and pigs), followed by feed production, chemical-intensive food production, and flooded paddy rice production, as well as deforestation caused by a desire to expand cultivated areas.
Forest fires, savanna fires, and volcanoes are all natural sources of GHGs and black carbon.
What exactly is black carbon, and how does it contribute to global warming?
Black carbon (BC) is made up of tiny carbon particles that are released as a result of incomplete combustion of fossil fuels, biofuels, and biomass. These particles are extremely small, ranging in size from 10 m (micrometres, PM10), the size of a single bacterium, to less than 2.5 m (PM2.5), one-thirtieth the width of a human hair and small enough to pass through the human lung walls and into the bloodstream.
Although BC – think of a plume of smoke from a chimney or a fire – falls out of the lower atmosphere in days, it absorbs the sun’s heat millions of times more effectively than CO2.
